3 Claims.

This invention relates to new and useful improvements in a double trapair mixing smoking pipe and the like.

More specifically, the invention proposes the construction of a smokingpipe characterized by the provision of a double trap located within thestem thereof for collecting juices and particles of tobacco from thesmoke entering the stem in a manner to permit only cool smoke to enterones mouth.

Still further it is proposed to characterize the pipe by a tobacco bowlAcontinuing at its bottom into a rearwardly extending stem portion havingthe first trap located therein for collecting juices as the smoke passesfrom the bowl.

Still further it is proposed to mount a mid stem section upon therearwardly extending stem portion of the bowl, provided with a secondtrap compartment in a manner to collect any juices not collected by thelrst'mentioned trap.

Still further it is proposed to provide a mouth bit stem section mountedupon .the free end of the mid stem section and provided with a smokepassage for conveying the cleaned smoke fron. the second trap sectioninto ones mouth.

Still further it is proposed Ito provide a passage between the trapsections through which the smoke is adapted to pass, and an auxiliarypassage adapted to be utilized for conveying the smoke in the event thatsaid first passage becomes clogged with juices or bits of tobacco.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which theVarious novel features of the invention are more particularly set forth.

The double trap air mixing smoking pipe, ac'

tion Illa. This rearwardly extending stem portion is formed with aninwardly extending opening II forming the first juice .trap compartment.

. means of an aluminum member I3 set into the bottom thereof and whichhas a reduced end I3a threadedly engaged into the passageway I2. Thisaluminum protector I3 is provided for the purpose of preventing thetobacco from coming in direct contact with the heel of the bowl toprevent the tobacco located within this area from becoming soggy whilethe pipe is being smoked.

A mid stem section I4 having a front end shoulder portion I4a isconnected with lthe rearwardly extending stem portion |08'. This midstem section I4 has its shoulder front end portion Me extended into therear portion of the stem portion Ilia. This mid pipe section I4 isfurther hollowed, as indicated at I4", for forming the second juice trapcompartment. This hollow Il!b extends inwards from the rear end of themid stem section I4.

A mouth bit section I5 is connected with the mid stem se'ction I4. Morespecifically, this mouth bit section I5 is provided with a front endshoulder portion I5a which is inserted into the rear portion of thehollow I 4b of the mid stem pipe section. This mouth bit stem I5 isfurther provided with a smoke passage I6 for conveying the smoke fromthe second juice trap compartment to the interior of ones mouth. Thefront end shoulder portion I4a of the mid stem section I4 is providedwith a coaxially extended opening I4c through which a tube I1 extends.This tube l1 has one of its ends partially extended into the first trapcompartment I4b and is provided for the purpose of conveying the smokefrom the first trap compartment to the second trap compartment.

The front end of the smoke passage I6 is enlarged, as indicated at i611,and carries a second tube I8. This .tube'l8 has its rear end extendedinto the enlarged opening Iiia and its front end extended partially intothe second juice trap compartment I 4b. This tube I8 is provided forconnecting the interior of the second juice trap I4b with the smokepassage I6.

The mouth bit stem section I5 is further provided with an air ventaperture I'9 extending from the top wall of the smoke passage to theexterior of the bit stem section I5. This aperture I9 is provided forpermitting a quantity of fresh air to enterthe smoke passage and mixwith the smoke passing therethrough in a mani or tobacco juice.

. the tube.

ner to cool the same before it enters the mouth. The operation of thisinvention is as follows:

The pipe is assembled as shown in Fig. 1 and the tobacco to be smoked isplaced Within the i hollow IIIb of the pipe bowl I0. The tobacco is thenlit and when one draws upon the mouth bit stem section the smoke willpass from the burning tobacco to the first juice trap compartment II.Within thiscompartment all juices and particles of tobacco will beseparated from the smoke before the same enters the tube I1. Furtherdrawing upon the pipe stem section will cause the smoke to pass throughthe stem II into the secoid juice compartment I 4b.

I ment acts to separate any juices or bits of to- This juicecompartbacco from the smoke which was not separated by the first juicetrap compartment to clear the 1 smoke of all juices before entering thetube I8. From the tube I8 the smoke will enter the smoke passage I6where it will be mixed with a quantity of vair entering the aperture I9to cool the smoke before the same enters the mouth.

From an inspection of Fig. 1 it will be noted that the pipe stem sectionI may be separated from the mid stern section I4 and that the mid stemsection may be separated from the rearwardly extending stem portionIllEL to permit each j of the juice trap compartments to be conveni- 1ently and thoroughly cleaned of any juices colg lected therein.

According to the modification of the invention shown in Figs. 6-8inclusive, the construction of the pipe'is similar to that previouslydei scribed, except for the provision of an auxiliary passage 20 betweenthe rst juice trap compartment II and the second juice trap compartmentMb and which is adapted to be used in the event tion Illa, and stillanother portion 2Gb formed in the front end-.of the mid stem section I4.These 1 portions arefadapted to be aligned with each other as shown inFigs. 6 and 7 for permitting the smoke to freely pass therethrough.However,`

when the tube II is clear it is more desirable to have the portions 2|)aand 2lib out of alignment so as to cause the smoke to pass only throughThe aligned position of these portions of the passage 20 is controlledby means of mark- 1 ings 2I and 22 formed on the adjacent ends of therearwardly extending stem portion Il)a and alignment.

. In other respects this form of the invention is similar to theprevious form `and like parts are identified by like reference numerals.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I the tube I'I becomes cloggedwith bits of tobacco j This passage 20 has a portion 20B formed in therearwardly extending stem porclaim as new, and desire to secure byUnited States Letters Patent is:

1.`In a smoke pipe, a stem portion having a cylindrical bore extendedinwards from its rear end forming a tobacco juice first trapcompartment, a mid-stem section having a front end shouldered portion ofa diameter equal to the diameter of said bore and extended into thefront of said bore, said mid-stem section being formed with a boreextended inwards from its rear end forming a tobacco juice second trapcompartment, said front end shouldered portion being formed with acoaxial passage for conveying smoke from said first trap compartment tosaid second trap compartment, and a normally closed' passage extendingbetween said compartments above said passage and substantially parallelthereto and being adapted to be used for conveying smoke when saidfirst-mentioned opening becomes clogged.
